Have a look at the global map on the webpages of the GTN-P Database. We have been working on improving and implementing new functions on it during the last days. Now you can display/hide boreholes and active layer monitoring sites and the map is equipped with a colour code to get an overview about different borehole depths and different kinds of active layer monitoring sites. By clicking on a point on the map you get more detailed information on the respective site and a link to it in the GTN-P Database.
